If you have a spell and you don't have all the ingredients, you may be able to swap out one thing for another. Check this list to see if you can substitute your hard-to-find item with something easier to obtain. Make sure you research your substitutions to make sure they really are what you're looking for and listen to your own intuition. Herbs can be used for different purposes and it's a good idea to thoroughly research the herb you're trying to substitute to determine its purpose in the spell and then thoroughly research potential substitutes for true compatibility. You can't just swap out one thing for another without really considering its purpose.

If you can't find what you're looking for here, find out the planetary correspondence of the item you're looking to substitute and visit that planet's page as a starting point. Ingredients that correspond to the same planet carry similar energies and can sometimes be used for the same purpose in a spell.

Keep in mind that these substitutions are for magic and spellwork only and should not be relied upon for healing or culinary use.

Please be careful with juniper . This isn't the only reason but….ted bundy used juniper trees to hide his last corpse and she has never been found. A blessing or cleansing from a third party should remove any malevolent energy from juniper. I know , it's not strictly in a book ,but, ………its a small concession.

That depends what you're using it for. If you look at the Narcissus article, you'll see that Daffodil corresponds to the element Water and the planet Venus, so you'll probably find suitable alternatives among plants with similar correspondences.

It doesn't matter what the spell is, what matters is the purpose of the herb in the spell. Lavender has similar effects on the mind as rosemary, but is more soothing and less stimulating. The oregano kick should offset that. Something else stimulating would too. Like peppermint.
